WEATH ER-STRIP.

SPECIFICATION. forming part of Letters Patent No. 293,' 738, dat ed February 19, 1884..

Application filed August 24, 1883.

To all whom it may concern/.-

Be it'known that I, JAMES H. HUMMEL, of New York, in the county of NewYork, in the State of New York, have invented new andv useful Improvements in Weather-Strips, of which the following, taken in connection with the accompanying drawings, is a full, clear,

and exact description.

This invention relates to the class of weather-strips in which an elastic packing-strip is secured to a firm sustaining-strip, which receives the nails or screws by which it is attached to the parts adjacent to the crevice to be closed.

The invention consists in an improved construction' and combination of the constituent parts of the weather-strip,whereby increased stability, durability, and efficiency are imparted thereto, as hereinafter more fully explained, and specifically set forth in the claim. The invention is fully illustrated in the annexed drrawings, wherein Figure 1 is an iso metric view of a portion of awindowprovided with my improved weather-strip. Fig. 2 is a detached enlarged plan view of the weatherstrip, and Fig. 3 is a transverse section of the same.

Similar letters of reference "indicate corresponding parts. 1

A represents the elastic packing-strip,com- 3o posed of sheet-rubber or other suitable elastic material, and B is its sustaining plate or strip, which receives through it the nails or screws by which the weather-strip is secured in its required position. Said sustaining plate I 3 5 form of a sheet-metal strip, which by suitable rollers or tools I bend concavo-convex in crosssection, and fold the longitudinaledges thereof into the concavity of said strip only part way toward the center "thereof, as shown at 40 a a in. Fig. 3 of the drawings, thereby imparting to it increased rigidity, and at the same time providing it with two separate and distinct bearings on the side adjacent to the surface to which the said sustaining-plate is to be attached. The elastic strip I firstv fold once upon itself longitudinally along the center thereof, as indicated by the reference-let ter b, and then fold the raw edges of said strip (No model.)

back part way the width of the doubled portion thereof. This elastic strip I secure in the concavity of the sustaining-strip by inserting underneath the folded edge a thereof the two raw edges of the elastic strip A, and tucking under the other folded edge, a, of the sustaining-strip the fourfold portion of the elastic strip, and pressing the metal folds down upon the embraced portions of the strip A, so

as to securely retain the same. The first longitudinal fold, b, of the elastic strip projects from under one of the folded, and thus reenforced,edges of the metal strip B, and forms a'tubular packing, which lies across the crevice to be closed, as represented in Fig. 3 of the drawings.

It will be observed that,- aside from the advantages hereinbefore set forth, the withindescribed construction and combination of the constituent parts of the weather-strip obviates the exposure of raw edges of either the rubber or metal, and presents a neat and perfect Fii'rthermore, by making the metal plate concave-convex in cross-section, it is stiffened and enabled to press more firmly with its doubled,and thus reenforced, edge on the elastic strip projecting from under it.

Having described my invention, what I claim as new is The elastic strip folded once upon itself along the center and back again from the raw edges part way the width of the double portion, in combination with the metal strip formed concavo-convex in cross-section, and having its edges folded into the cavity part way toward the center thereof, and embracing, respectively, the raw edges and fourfold edge of the elastic strip, substantially .as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the 0 county of Onondaga, in the State of New York, this 22d day of August,'188 3.
